Abstract: 765,738. Make and brake switches mechanical. I-T-E. CIRCUIT BREAKER, CO. July 20, 1953 ]Aug. 29, 1952], No. 20101/53. Class 38(5) In switches for use in contact rectifying systems including switching chokes such as form the subject of Specificat ion 765,737 [Group XXXV] the contacts are operated through push rods whose lengths can be adjusted to vary the contact time while the rectifier is under load. In a three - phase bridge - connected circuit, Fig. 1 (not shown), a pair of switches is associated with each phase to connect it at appropriate times to the positive and negative D.C. bus-bars respectively. Figs. 2 and h show one pair of switches 70, 71 (described in detail in Specification 765,739) in which movable contacts 30, 31 carried by push rods 62, 63 are driven up and down 180 degrees out of phase by an synchronous motor 40 acting through eccentric 42 and bell crank 50, to connect and disconnect alternately contacts 27, 28 on phase bus-bar 10a with contacts 25, 26 on D.C. bus-bars 21(-) and 20(+). The length of push rod 62 (like that of all six rods) is varied by manual rotation of worm 108 which meshes with a worm wheel 106, rotation of which turns the upper part of the push rod which thereby moves axially as a result of its screw engagement 110, 111 with the lower part. The latter part cannot rotate because of its slot and bar engagement 117, 118 with pin 60 journalled in bellcrank 50. Worm wheel 106 is held by spring 150 against a fixed support 107. Engagement between internal and external splines 105, 101 on the worm wheel and push rod respectively allow relative axial movement without relative rotation. Return springs 116 and 80 keep the push rod and moving contact 30 against the pins 60 and push rod respectively. The push rod slides in a housing 125 and is force fed lubricated by oil through port 128 from oil chamber 129. The push rod carries oil drip shields 130, 131, 132 at its upper ends. For determining the necessary adjustment of the contact times, an oscilloscope is so arranged that it can be connected across any one of the six pairs of contacts, Fig. 1 (not shown). The adjustment of opening and closing may be determined from comparison of each oscillogram with the desired ideal, Fig. 9 (not shown) as explained in the accompanying chart, Fig. 10 (not shown).

Abstract: 261,081. British Thomson-Houston Co., Ltd., Clinker, R. C., and Kinman, T. H. Aug. 11, 1925. Crystal detectors.-A lost-motion connection is provided between the adjusting device of the movable element and the element itself so as to prevent undue pressure being applied between the two elements. As shown in Fig. 1, the movable crystal cup b is mounted on a rod c having a head e slidable in the recess f of an operating knob d. The desired pressure between the crystal is provided by a spring h, excess pressure being prevented by reason of the loose connection between the head e and the knob d. The friction between the head e of the rod and the knob is sufficient to cause rotation of the cup. In the modification shown in Fig. 2, the rod c has a head e which moves relatively to the cup b when pressure is applied to the knob d.
